To all tolto/'ri 'it vmay concern.'

Re it known tl'iat lf, W iLsoN lil. SYMoNs, a citizen ol" the. UnitedStates, residing at Chi cago, in the county olt (ook and State. of'lllinois, have invented a new and useful Ventilating System, ol' whichthe following is a speci- 'lit-.ation This invention relates to meansfor ventilating passenger cars, either d aycoaches, parlor cars,sleepers or the like..

The primary object of the ln'esent invention to provide a novel andpracticable system that can be readily installed, and with which eachpassenger may control and regulate a supply of fresh air to himselfindividually without causing discomfort or inconvenience to otherpassengers who may be of a different teinl'ieranient or disposition.

A further object is to provide in a system of the above character, meanswhich will insure a supply of fresh air when the ear is moving in eitherdirection or is at a standstill, filtering and stop mecl'ianisins beingprovided that will eliminate cinders and dust as well as prohibit theingress of water.

The )referred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of a carequipped with the improved system. Fig. 2 is a detail view, showing aportion of the car broken away in order to illustrate the abovemechanism. Fig. 3 is a cross sectional view through the car. Fig. 4 is alongitudinal sectional view through a portion of the saine. Fig. 5 is adetail view, showing the discharge end of one of the lateral pipes. Fig.6 is a sectional view therethrough.

tion. Mounted longitudinally upon the roof thereof on opposite sides ofthe deck lights are air conduus 126. 'lhcse conduits are connected attheir ends by oll'scts 14 and upstanding goose necks 15 with thesnialler ends olI longitudinally disposed funnels 16. rlhe open ends ofsaid l'unnels are covered by screens 17. It will be noted. that portionsof the sides of the funnels are parallel and that the tops and bottomsare convergently disposed. lnwardly swinging valves 18 are pivoted attheir upper ends, as shown at 19, within the upper portions of thefunnels between the. parallel portions of the side walls, while theirinner and lower ends are arranged to abut against stop ribs 20 securedto the bottoni walls of the tunnels. W hen moved by an inrushing currentof air, they can swing inwardly and upwardly,A but if the air attemptsto flow outwardly through said funnels, the valves are automaticallyclosed, as will be evident, the valves being located and operai-in@wholly in advance of the goosenecks. n the goose necks are preferablylocated spaced overlapping bafiie plates 21, but these are not entirelynecessary and may be dispensed with if desired. The bottom of eachfunnel inc-lines downwardly towards its out-er end from the goose neck,as will be evident by reference to Fig. 9. While under ordinaryconditions, funnels at the ends of the pipes will probably besufficient, corresponding tunnels 16a may be located at intermediatepoints, and connected to the longitudinal conduits by correspondin goosenecks 15a, as illustrated in Fig. 1. he two longitudinal conduits 13 arepreferably connected. by a transverse conduit 22 extending over the topof the car, illustrated in Figs. 1 and 8.

Connected to the end portions of the air conduits and preferably to theterminal goose necks are delivery pipes 23 that extend from fan casings24, which may be suitably located within the car, as shown in Fig. 3, ormounted on the top thereof. l'nwardly opening swinging valves 23a arelocated in the delivery pipes 23, and operate 1n the same manner as tieautomatic valves 18 of the funnels. Supply pipes 25 are also connectedto the casin s, and have screened inlet ends 26 dispose exteriorly ofthe car, and preferably downturned. Within the fan casings 24 aremounted suitable electric fans 27, which may be of any well known type,and supplied from any suitable source of power.

lef 'A lurality of lateral pipes28cxtend downwar ly from thelongitudinal conduits 13 between the inner and outer sections of theside walls, and. have delivery ends 29 disposed in convenient relationto the passengers or occupants of the seats, compartments or berthsaccording to the character of the car. ln the preferred forin ofconstruction, these outlet ends open into chambers 3() closed by screencaps 31 screwed thereupon and liaviiig Alltering material 32 arranged insaid chambers. Cloth coverings preferably extend over the screens, andare held in place by flexible bands 34. These coverings can. be readilyremoved and replaced by clean ones as o'lten as found desirable ornecessary. The chainbers 30 are preferably inounted on detach ablepanels 35, and extending through said panels directly above thechambers, are steineJ 36 of controlling valves P7, said valves in thepresent embodiment being rotatable, though any desired type may beemployed. chambers 30, which project within the car,

furthermore constitute nipples upon whichA the inlet ends 38 of flexiblehose sections 3Q may be placed, these sections having foraniinousdischarge nozzles 40 at their free ends.'

Branch pipes 41 lead from the pipes 23 at the ends of the car, and areconnected to a common dischargespout 42, which teinii nates in anadjustable ilared nozzle located directly over the coinpanionway oraisle of the car. As shown in Fig. 13, the nozzle 43 preferably has aball and socket y connection -44 with the spout 42, which permits theadjustment of the nozzle in any di- ',rection, the friction beingsufiicient to .hold

said nozzle as positioned. Instead of this arrangement, the structuredisclosed. in Fig. 14 may be employed, wherein the branch pipes aredesignated 41, and the spout 42a consists of a flexible hose, to the endof which is secured the nozzle 43". Valves 45 and 46 are preferablylocated in the pipes 23, and branches 41 so that the passage of airthrough either may be readily controlled.

The o eration of the system may be briefly outlinedp as follows. As longas the ear is moving in one direction or the other, the valves 18 in thefunnels facing the front ends thereof will be swung to open position bythe inrushing air, while the valves in the funnels facing the rear end,will be held in closed condition by the air pressure within theconduits. In like manner, the valves 23UL will be closed. If now apassenger desii'es fresh air, he has only to open the valve 37contiguous to his seat, whereupon the air in the conduit will passthrough the lateral pipe, through the filtering material, and bedelivered in close proximity to said' assenger. Thus, each passenger cancontro an indi vidual supply of fresh air without consulting or causinginconvenience to any other assenger. In case, a supply of air is desiredThe -out securing fresh air freni the outside.

by a person in a reclining position, one of the hose, sections 3) may beattac-hed to thel iiltering (',liainlier 3() and the nozzle may lie heldas desired, as shown in li`ig. 4. 'lliese hose sections may he ofdill'ei'ent lengths, andv can lie kept in stoel: to be, supiilied bythe. porters on request. Yi'heii the train is at a stai'idstill, thecoi'uluetor or ti'iL-iijinien have only to cut in the electric lans, andthus insure a proper air pressure or supiily, when the saine would beotherwise lr ring. lt also will be observed by means iff the. branchpipes 41 and delivery nozzles 4B, the aisle or passageway of the ear canhe readily ventilated with air from the outside and the supply through.the lateral pipes 28 or tl'irough the lirai'iches 4i. can be iriadilycontrolled. This latter niechanisniis particularly uselul .inminneetioii "with i-.leepers l t is well known that these cars are oftenplaced at stations and are opened for passengers in the earlycvei'iiiig, whereas they are not moved out of the station until lateinght. lt is als-: i well known that very little ventilation is securedwhen the car is at a stand- S .-i fil. t itat-,Auw .ie-.vic 'i (i till,ii l r'lrrt* luv "lern in de reentljj t overcome this -obJection byplacing i'ans in the cars.

lt will be observed that in this system. therefore an adequate supply offresh air is provided fer each passenger, as already outlined, this airis free from dust and eiiiders, and the mechanism is such that' no watercan drive into it. Moreover, by having* the conduits on opposite sidesof the connected by the transverse conduit, if the fans en one sideshould from any cause, becoine inoperative, air will be supplied to theentire system from the fans on the other side only.

Frein the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be app l rent totl'iose slrilleril in the art, without further description, and it willbe understood that various changes in the size, shape, projiiortion, andminor details of construction, may be resorted to without departing fromthe spirit or sacii'lifving any of the advantages of the invent-ien.
